To all whom, t may concern:

Be it known that I, MARCUS A. COYKEN- DALL, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented certain new and useful Improvements in- Flushing-Spittoons; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in flushing-spittoons and its object is to provide means whereby in the event that the same should be iilleld with water from any cause the supply of water would be automatically cut ed and overflow of the'same prevented.

My device consists,essentially,of a flushingspittoon mounted upon a.yi'elding.support, a valve interposed in the water-supply circuit for flushing the spittoon, and means for automatically closing the valve whenever from any cause a predetermined quantity of water accumulates in the bowl, as will hereinafter more fully appear by reference to the accompanying drawings, in which#- Figure lis a vertical section ofV a device embodying my invention, taken on the' line 1 l of Fig. 2; and Fig. 2, an enlarged horizontal section taken on the line 2 2 of Fig. l1.

Like letters refer to like parts in both of the gures. z

vA represents the bowl of the spittoon, .having attached a drain-pipe B, provided with a reduced portion B', said drain-pipe `forming the support for the' bowl and vertically movable in any suitable support C. For. the yielding support I prefer to use a spring' D, surrounding the reduced portion B of the drainpipe and engaging a suitable shoulder on the saidpipe, said spring beingadapted to normally retain the bowl in an elevatedposition,l as shown in the drawings. 'To-adjust the tension of said spring, a vertically-adj ust- `able sleeve E is provided, surrounding the reduced portion of the drain-pipe and having screw-threads engaging corresponding threads in the opening in the support C.

G is a detachable collar to limit the upward go movement ofthe drain-pipe in the support.

4of water. is connected to the pipe H and receives the water therefrom, and the end chambers of the case are connected by `means of a by-pass lK and ports K. which areopposite the partitions J when the valve is moved to closed position are adapted and preferably provided with screw;

threads engaging the threads on the sleeve, whereby said flange may be used as a locknut to secure the sleeve E in place when adj usted by turning the said flange against the under side of the support C. This flange eX- tends outward a sufficient distance to engage the lower end of a valve-rod R, having a 1011-,

has attached thereto at its outer end a valve-- case I, surroundingabalaneed valve L. This case is divided into three chambers by transverse partitions J, having central openings in which the valve L is movable. The upper chamber is connected to a suitable pipe N lto `vconvey water to the Hush-pipe' P', to which latter the water is admitted by a valve O and pipe connection P. The pipe N is also v'extended upward at Q for Vthe purpose of drawing water for any convenient use and provided with a valve O to control the ow The middle chamber of the case I The portions of the valve to fill the openings in said partitions, and

thus retain the water in the middle chamber of the case, and the portions of the valve opposite saidpartitions when the valve is moved to open position, as shown, are recessed, as

at L', to permit the water to :tlow through from the middle chamber t the end chambers. These chambers in the case surround the valve, and lthe recesses L' are on all sides of the valve. The pressure in the middle chamber is thus balanced in all directions, and the pressures in the end chambers are directly opposite and equalized through theby-pass.

IOO

The valve is thus perfectly balanced against both the forward and back pressures and moves freely under all conditions.

To open the valve L, a spring M is provided in the upper chamber, which engages the end ofthe said valve and the end ofthe pipe N and yieldingly holds the valve open. By properly adjusting the sleeve E the tension of the spring D will be such that whenever water for any reason accumulates in the bowl A its weight, added to that of the other parts supported by the spring D, will depress the said spring and move the bowl and parts attached thereto downward. The contact of the flange F with rod R willsupport the valve L, and as the surrounding case descends the openings in the partitions will be automatically closed and the iow of water to the bowl shut ott. The ange T being circular, the bowl may be rotated about its axis and the end of the rod will traverse the fiange and remain in contact therewith.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of a bowl, a yielding support for the same, a pipe to supply water for iiushing the bowl and a valve adapted to cut off the flow of water in said pipe and means for closing the valve by the downward movement of the bowl.

2. The combination of a bowl, a pipe attached to the bowl for flushing the same, a balanced valve inserted in circuit with the pipe, a vertically-yielding support for the bowl, and an unyielding support for the valve, whereby the valve is closed when the bowl descends.

3. The combination of a bowl, a pipe attached to the bowl for iushing the same, a valve-case in circuit with the pipe, a vertically-movable valve in the case, a drain-pipe attached to the bowl and vertically movable in a support, a spring supporting the drainpipe and yieldingly supporting the bowl, and an unyielding support for the valve.

4. The combination of a bowl, a drain-pipe having a reduced portion and vertically movable in a support, a spring surrounding the drain-pipe and supporting the same, an adjustable sleeve in the support and supporting the spring, a pipe to conduct water to the bowl, a valve-case inthe circuit of the pipe, a vertically-movable valve in the case, and having a stem extending downward therefrom, and an unyielding support engaging the valve-stem.

5. The combination ofa bowl mounted upon a vertically-yielding support, a pipe to sup` ply water for flushing the bowl and vertically movable therewith, a valve-case in the circuit of the pipe, partitions dividing the valve-case into three parts and having openings for the valve, a valve adapted to close said openings and longitudinally movable therein, and also having recesses to permit water to flow through said openings, a by-pass and ports connecting the end portions of the case, a stem connected to the valve to move the same and a support to engage the stem and support the valve, and a spring engaging the valve to open the same.

6. The combination of abowl, a drain-pipe attached to the bowl and vertically movable in a support, a spring yieldingly supporting the drain pipe, means for adjusting the spring, a supply-pipe in the axis of the drainpipe and extending through the side thereof, a valve-case attached to the end of the supply-pipe, a balanced valve in the case, a downwardly-extended stem on the valve, a ange engaging the stem and attached to the support, a spring engaging the valve to open the same, and a pipe extending upward from the valve-case and connected to a flushing-pipe in the bowl.

7. The combination of a bowl, a verticallyyielding support for the bowl, means for adjusting said support, a valve-case attached to the bowl and movable therewith, partitions dividing the case into three chambers and having central. openings, a valve longitudinally movable in said openings and adapted to close the same, and having recesses opposite said partitions when the valve is open,a by-pass and ports connecting the end chambers of the case, a supply-pipe connected to the middle chamber of the case, a pipe inserted in the end of thecase and extending upward therefrom, a flushing-pipe in the bowl and connected to the said last-named pipe, a spring engaging the valve to open the saine, a stem on the valve and having an adjustable end, and an unyielding support engaging the valve-stem.
